IMPROVEMENT IN PENCILS.

Specification forming part of Letters Patent No. 205,797, dated July 9,1878; application filed February 8, 1878.

To all whom it may concern:

Be it known that I, EDWIN O. HAVILAND, of Sydney, in New South Wales,have invented a new and Improved Revolving Pencil, of which thefollowing is a specification:

Figure 1' is a side elevation of my improved pencil. Fig. 2 is alongitudinal section. Fig. 3 is a transverse section on line at x inFig. 2. Fig. 4 is a transverse section taken on liney y, Fig. 2.

Similar letters of reference indicate corresponding parts.

The object of my invention is to provide a pencil which may contain leadof different colors or of difi'erent degrees of hardness, any

one of which may be brought into use whenever required.

The invention consists in the combination of a pivoted barrel, with aholder for the leads, and a stop for retaining the holder in anyrequired position.

Referring to the drawing, A is a barrel, bored centrally throughout itsentire length to receive the rod B, the front end of which rod isjournaled in adiaphragm or plate, f, of a nozzle, D, so that the barrelcan revolve with the rod. Instead of this construction the barrel mayturn on the rod, which thus serves as an axis-pin, the rod, in bothinstances ,of the construction described, being secured in the diaphragmby riveting or headin g the end thereof, as is shown in Fig. 1.

The barrel is traversed longitudinally by several holes, a, forreceiving leads of different colors or of the same color, havingdifferent degrees of hardness.

The nozzle D has a rear socket for receiving the front end of therevolving barrel or magazine, and its split tapering tube E projects inline with one of the holes a in the barrel A. At the side of the nozzleopposite the tube E there is a spring-bolt, b, which engages one of thebores or lead-chambers in the barrel A, and prevents the nozzle fromturning.

The tapering split tube E is threaded externally, and upon it a nut, c,is placed, by turning which the lead is tightened or loosened. The nutmay be milled or roughened, to facilitate the manipulation thereof. Ahead, F, is screwed on the end of the rod B to retain the barrel A andto hold the leads in the holes a.

Leads of various colors are placed in the different holes, and theircolor is indicated by a stripe of similar color on the outside of thebarrel. When it is desired to use a lead of a particular color the spring-bolt b is withdrawn, and the barrel A is turned until the desiredcolor is opposite the split tube E. The springbolt is then allowed toenter one of the holes a, and the pencil is placed in a verticalposition with the nozzle downward, when the lead drops into the splittube, and may be clamped by turning the milled nut c. The barrel isfilled with leads by removing the head F and inserting them in the upperend of the pencil.

I do not limit or confine myself to the particular form or arrangementof parts herein described, as they may be varied without departing frommy invention.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- 1. Apencil having a revolving many-cham bered barrelor magazine for leads, a nozzle or cap-piece adapted to receive and holdthe leads from any one of the chambers, and a device, substantially asdescribed, for lockin the barrel to the nozzle, as and for the purposeset forth.

2. The combination of the revolving barrel A, nozzle D, having the splittapering tube E, the rod B, and head F, substantially a s shown anddescribed.
